3.3.a Implement and troubleshoot static routing

A router can learn about remote networks in one of two ways:

● Remote networks are manually entered into the route table using static routes.

● Remote routes are dynamically learned using a dynamic routing protocol.

Static routing provides some advantages over dynamic routing, including:

● Static routes are not advertised over the network, resulting in better security.

● Static routes use less bandwidth than dynamic routing protocols, as routers do not exchange routes.

● No CPU cycles are used to calculate and communicate routes.

● The path a static route uses to send data is known.

Static routing has the following disadvantages:

● Initial configuration and maintenance is time-consuming.

● Configuration can be error -prone, especially in large networks.

● Administrator intervention is required to maintain changing route information.

● Does not scale well with growing networks; maintenance becomes cumbersome.

● Requires complete knowledge of the whole network for proper implementation.
